In case you missed it, here is a link to a multi-page and a fairly large read of how to build, setup, software explained, print, calibrate, set slicer's, etc. document. Although the layout and format is a little outdated, the data in there is one of the best and comprehensive I have come across. IMHO it is a must read for those just starting out, or if you just want to know more about a Prusa type printer. Check it out:
